The invention provides a cool pack arrangement comprising a base cool pack 30 having a plurality of edges 36; and a plurality of side wall cool packs 32 to 35 each arranged to be located on or against a respective edge of the base cool pack 30, wherein the base cool pack 30 has a fill point 37 protruding from one edge and at least one blanking protrusions 38 protruding from at least one other edge in a position along that edge corresponding to the position at which the fill point protrudes from its edge, wherein each side wall cool pack 32 to 35 has a recess 46 in a first edge which, when the side wall cool pack 32 to 35 is located on or against the base cool pack 30 accommodates either the fill point 37 of the base cool pack or a blanking protrusion 38, depending upon which edge of the base cool pack the side wall cool pack 32 to 35 is located on or against. The invention permits two types of cool pack to be assembled into a complete cube (or similar) cool pack layer, which cool packs are located closely together in a manner that the layer of cool packs can act as an efficient barrier to thermal convection currents. The invention may have particular application to passive insulated shipping containers. |
